There are two main types of stents: a bare metal stent (BMS) and drug eluting stent (DES). Drug-eluting stents have recently become more widely used due to their demonstrated effectiveness in delivering restenosis-suppressing medication through a coated metal material. An interventional cardiologist will determine the appropriate type of stent to implant depending on a patient's individual case.
